This is very true,
My partner's step father is very well known in the business world, he made most of his money via dodgy investments and recently had to pay £millions in HMRC fines
He's literally hoarded all of his cash, he has around 5x Ferraris, and a whole load of other insane cars - his children have had to struggle and borrow money off their other relatives so they could claw enough deposit for a house, and a whole load of other stuff - meanwhile he's just buying insane cars and houses, he also likes to go to Saville row and spend a few grand on shirts every week or so, it's totally ridiculous.
